* Full Lesson* Chemistry: Group 7 Elements/Halogens

This is a full lesson looking at the properties of Halogens in Chemistry. It was originally delivered to a year 8 class but could easily be adapted for other key stages and year levels. This is designed for a 100 minute lesson but could be broken up into smaller parts.
During this lesson, pupils will:

• Recap knowledge of Alkali Metals/Group 1 elements.
• Begin to identify the properties of halogens (Chlorine)
• Identify the Halogens on the periodic table
• Interpret data to deduce the melting and boiling points of halogens.
• Use melting and boiling point date to decide the state of matter of halogens at room temperature.
• Watch videos to gain an understanding of the chemical and physical properties of Halogens.
• Investigate the reactivity of halogens.
• Investigate displacement reactions of halogens.
• Write word equations to demonstrate knowledge of displacement reactions.
